abstract = {A novel, cost-efficient, all-ceramic Solid Oxide fuel Cell
(SOFC) is investigated in the project KerSOLife100 funded by
the German Ministry for Economic Affairs and Energy (BMWi).
The design includes a low-cost mechanical support material,
and an alternative cost-efficient production route is
applied. The support material is a porous membrane made of
doped forsterite (Mg2SiO4), placed adjacent to the cathode
(air) side of the cell. The alternative manufacturing route
involves a single step co-firing process of the forsterite
and all functional layers. The co-firing temperature is
currently set to <1300°C, which is significantly lower than
the maximal temperature applied in the usual SOFC
manufacturing sequence. So far, the effects of the use of
forsterite as support material and the co-firing production
route on the performance and the lifetime of this SOFC
concept are scarcely examined. Thus, the present
investigations are analyzing the interactions between the
forsterite support material and a cathode material occurring
during the high temperature sintering step. The cathode
material investigated in this study is LaxSr(1-x)MnO3, which
is generally known for its high chemical stability
relatively to other available cathode materials.
Inter-diffusion and secondary phase formations between the
layers are characterized by means of energy dispersive X-ray
spectroscopy and X-ray crystallography. As well, the outcome
of the co-firing on the macro scale geometry and the
microstructural properties of the cathode is evaluated.},
